Enum RenderError 

pub enum RenderError {
    MalformedAddr {
        sheet: String,
        addr: String,
    },
    MalformedMerge {
        sheet: String,
        range: String,
    },
    NonFiniteValue {
        cell: String,
    },
    Writer(String),
}

A fallible render failure (review item 8 — the writer value path is panic-free; a malformed coordinate / non-finite value / writer error surfaces as an Err, NEVER a panic and NEVER a bogus cell). Owned String detail to match the crate’s LintFinding error style (no borrow across the API).

Variants

MalformedAddr

A cell’s A1 address in the descriptor did not parse to a (row, col) coordinate (T-12 panic-freedom — a malformed addr is an Err).

Fields

sheet: String

The owning sheet name.

addr: String

The A1 address that failed to parse.

MalformedMerge

A merge range in the descriptor did not parse into two valid endpoints (or is degenerate / out of order).

Fields

sheet: String

The owning sheet name.

range: String

The merge range that failed to parse.

NonFiniteValue

A computed value for a cell was a non-finite f64 (NaN/Inf), which Excel cannot represent (handler.rs WR-06 reuse, T-12-05) — never written as a bogus number.

Fields

cell: String

The cell_key (sheet!addr) whose computed value was non-finite.

Writer(String)

The underlying rust_xlsxwriter writer returned an error (e.g. a name or dimension limit). Carried as an owned String (the crate’s error is not Clone/Eq).

Trait Implementations

impl Clone for RenderError

fn clone(&self) -> RenderError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RenderError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for RenderError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for RenderError

impl Error for RenderError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for RenderError

fn eq(&self, other: &RenderError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
